Rob Schneider's infantile cross-dressing routines fill "The Hot Chick," the latest gimmick from this unimaginative comedian. Schneider, a "Saturday Night Live" cast member from 1990 to 1994, is known for his one-note skit on that show, in which he played an office weirdo fixated on a copy machine, and two tepid comedies: In "Deuce Bigalow: Male Gigolo" and "The Animal," Schneider played schmucks who, through some accident, were thrust into another role. Forced comic situations ensued. In "The Hot Chick," Schneider is Clive Maxton, who runs across high school hottie Jessica (Rachel McAdams) while robbing a gas station. Jessica, a cruel-girl prototype from countless teen movies, has bought a pair of golden earrings with magical properties. When the two cross paths, their personas swap bodies, trapping each under the other's skin. Gender confusion is the name of this comic game.

Schneider and director/co-scripter Tom Brady stage routines meant to show the humor of a woman's horror at being trapped inside a man's body. The bits miss the mark, mostly due to Schneider's complacency as a comedian. Schneider fails to ignite the movie's anarchic scenes--a pillow fight between the "girls," for example--and appears lost during quieter moments.

The icy McAdams, who essentially disappears for most of the middle of the movie, doesn't make much of an impression. Anna Faris from "Scary Movie" plays Jessica's best friend and Matthew Lawrence, Joey Lawrence's brother, is the hunk boyfriend. Adam Sandler also makes a cameo appearance as a stoned bongo player.
